Question

Can anyone help me with Physics problem, please?
1.(a) What is the minimum impulse needed to give a 275-kg motorcycle and rider a velocity of 20.0 m/s [W] if the motorcycle is initially at rest? (b) If the wheels exert an average force of 710 N [E] to the road, what is the minimum time needed to reach a velocity of 20.0 m/s [W]?

2.A 1.26-kg brown bocce ball travelling at 1.8 m/s [N] collides with a stationary 0.145-kg white ball, driving it off at 0.485 m/s [84.0 W of N]. (a) What will be the velocity of the brown ball immediately after impact? Ignore friction and rotational effects. (b) Determine if the collision is elastic.
